HYD RANT-VALVE.

SPECIFICATION forming part of Letters Patent No. 238,879, dated March 15, 1881.

Application filed December 30, 1880. (N0 model.)

To all whom it may concern: I

Be it known that I, JOHN FLANAGAN, of Newburg, in the county of Orange and State of New York, haveinvented a new and useful Improvement in Hydrant-Valves, of which the following is afull,clear, and exact description.

The invention consists in combining with a hydrant-case having a side aperture and an apertured extension a cross-slotted cylinder provided with annular exterior packinggrooves and a valve sustained at the center by arms and carrying at the lowerend a packing-disk, as hereinafter described.

In the drawings, Figure l is avertical section of a hydrant of my improved construction. Fig. 2 is a horizontal section on line y y of Fig. 3, which is a vertical section, show- I ing the valve and the waste-rin gs.

Similar letters of reference indicate corresponding parts.

A is the hydrant-case, which is made preferably in the two portions, as shown, the upper part attached to the lower by flanges and bolts, and the lower portion formed with wasteopenings to a and a thread-extension, b, for connection to the main.

B is the valve-rod, consisting of a pipe fitted withwa-ste-rings 0 0 and valve 01, and carrying the nozzle d, that projects through an elongated opening in case A, so that the nozzle can move up and down with the valve-rod.

The elbow by which the nozzle 6 is connected is formed as a cap, closing -the upper end of the pipe, and with a solid rod, f, to which is connected, byaswivel-joint, g, a screw-rod, h, that passes through a threaded aperture of the cap t on case A. The rod It has a hand-wheel for its operation to raise and lower the valverod. The rod B may, however, be fitted for operation by a cam or other suitable device.

The rings a are formed by a cylinder, slotted crosswise, and made with annular grooves exteriorly toreceive packing-rings, so that the rings fit the case A snugly. With these rings is formed the stem and valve d, sustained at the center by arms 11. The lower endot' the valve projects below the rings, and

carries a packing-disk to cover the aperture from the extension I), which aperture, as shown, is fitted with a screw-ring seat for the valve.

The lower, waste-aperture a is placed so that it is uncovered by the lower ring a when the valve 611 is closed and covered when the valve is raised. The upper aperture to is covered by upper ring 0 when the valve is open for the escape of water that may leak into case A; but this upper ring and aperture are not essential, and may be dispensed with.

It will be seen that when valve 01 is open the water will pass directly through the rings to the pipe-rod B withoutturn-s. When the valve is closed the water in the pipe Bis free to waste by the lower opening a.

. The valve and rings may be fitted with a solid screw-rod, or with a solid rod fitted with a handle for raising and a spring for forcing it down. The nozzle in those cases will be a fixture on case A, and the water will pass through ring ointo the case. One ring and waste-aperture only will be used.

By this construction there is free passage for the water from the main by a single opening of ample size, and the waste-openings can be placed close to the bottom of the hydrantcase; so as to almost entirely empty the case.

aperture to and the apertured extension 12, of

the cylinder 0 0, having median cross-slot, an-

nular packinggrooves on the outside, and a' valve, 61, sustained at the center by arms d, said valve carrying at the lower end a packing-disk, as and for the purpose specified.
